Whenever we complete a test we are told what the "average score" is. How is this average score calculated? Does it only count the average score of the questions the first time answers a user submitted? Or for instance, the total number of times it was attempted (thus, the average scores would be higher cuz many people would be scoring higher on repeat questions).

Not sure why I want to know... but it seems on Unused Qs I do a little worse than the average test scores... I want to know if it's because I'm truly below average or just because the average score is inflated (cuz of 2nd passes). Thx =)
